General Manufacturing

Manufacturers need to assure their customers that their products will function as promised, and one of the primary ways to do this is documentation from an independent laboratory. Here at NSL, we characterize numerous products, including huge springs, tiny stents, wrenches, jet engine fan blades to may a few.

In addition to proper function, manufacturers also want to guarantee that their products are free of lead and other hazardous or regulated materials. For this reason, here at NSL we analyze electronic circuit boards, toys, and products that contain a variety of materials. In addition, the U.S. Consumer Product Safety Commission mandates certain tests for a range of products.

We do extensive analyses of aerospace forgings made of advanced high-strength steels, stainless steels, titanium, and nickel-base alloys. For example, to evaluate landing-gear forgings, we do impact testing, stress rupture testing at elevated temperatures, and tensile testing at elevated temperatures. We also do metallographic analyses for microstructure, and macroscopic examination to evaluate grain flow.

Automotive component manufacturers send us a wide range of parts for evaluation, characterization, testing, and failure analysis. For camshafts and crankshafts, we test for case depth to be sure that the heat treating process was successful, analyze for correct chemistry and microstructure, and test for mechanical properties such as hardness, strength, and ductility.

Another important service we provide manufacturers is that of reverse engineering for replacement parts in outdated equipment. We determine the chemistry of the alloy and how the part was made by carrying out a series of physical and mechanical tests. We reverse engineer bearings, which frequently include multiple components such as steel, alumina, and hard chrome, with elastomer seals and a plated or thermal spray coating.

No matter what the material or product manufactured, at NSL we pride ourselves on precise data, reliable results, and rapid turnaround. NSL Analytical Services is equipped to perform a variety of General Manufacturing materials testing services. Request a quote today!
